SN04-N NPN NO Distance Proximity Sensor Switch Module

SN04-N NPN NO Distance Proximity Sensor Switch Module
The SN04-N NPN Distance proximity sensor switch module is a 5mm distance detector that will detect the presence of a metallic object within 4mm of the surface of the sensor. The distance that the proximity sensor switch detects may vary with respect to the size and material of the object. 
This SN04-N NPN distance detector features an LED indicator and is manufactured with materials that antivibration, dust, water, and oil prevention.
